Sam Walker was pronounced dead on the scene at 9:37 a.m., according to the Cook County medical examiner's office. The medical examiner's office gave his address as being in the 1200 block of North Harding Avenue, but court records indicate he more recently used an address in the 600 block of North Central Park Avenue.

Police said Walker had been shot multiple times.

Earlier this morning, a 20-year-old man was wounded in a shooting in the city's South Chicago neighborhood, police said.

The man told police he was standing on the sidewalk when he heard shots, and soon after felt pain in his upper left arm, said Estrada. The man ran to the 8200 block of South Coles Avenue where he was found by Chicago Fire Department paramedics.

He was taken to Advocate Trinity Hospital, where his condition was stabilized, said Estrada.
